FILING-CASE.

Specification of Letters Patent.

Patented Nov. 12, 1912.

Application filed October 4, 1910, Serial No. 585.170. Renewed September6, 1912. Serial No. 719,004.

To all whom it may concern:

Be it known that I, JAMES FRANK DUN- EAVY, a citizen of the UnitedStates, residing at Newton, in the county of Middlesex and State ofMassachusetts, have invented certain new and useful Improvements in FilingCases, of which the following is a specification.

My invention relates to filing cases of that class which comprise aholder or box within which is arranged a follower that is adjustable tosuit the size of the contents of the holder with provision for securingthe follower in its adjusted position so that the pressure of thecontents of the holder on the follower will not displace the latter andsaid contents will be held properly within the holder.

The object of my invention is to provide an improved filing case of thistype and one wherein the follower may be quickly released and adjusted.

My improved filing case comprises a holder, a clamp slidably connectedwith the holder, a clamp operating member movably connected with theclamp and a follower connected with the clamp operating member, theparts being so arranged that when the clamp is unset, said clamp, theoperating member and the follower may be adjusted back and forth andwhen set said parts are locked to the holder.

The distinguishing feature of my improved filing case is the provisionof a clamp operating member connected with the follower and clamp sothat the latter operates responsively to the tilting movements of thefollower, the clamp being unset when the follower is moved in onedirection and set when the follower is moved in the opposite direction,and the pressure of the contents of the holder on the follower tendingto tilt the latter in a direction to hold the clamp set.

In the accompanying drawings :Figure 1 is a longitudinal sectional viewof a filing case embodying one form of my invention. Fig. 2 is a planview of a portion of the filing case shown in Fig. 1, showing theslidable clamp and the clamp operating member. Fig. 3 is a view similarto Fig. 2, but with the clamp operating member broken away in part. Fig.4: is a plan view of the clamp operating member. 'Flg. 5 1s a sec tionon the line 55 of Fig. 1, showing the clamp in its unset position. Fig.6 is a view similar to Fig. 5, but showing the clamp in its setposition. Fig. 7 shows in side elevation the sliclable clamp, the clampoperating member and a part of the follower that is fastened to thelatter.

Having reference to the drawings, A is the box or holder forming part ofmy improved filing case; B the clamp slidably connected with the holderA; C the clamp operating member, and D the follower.

E represents the usual removable rod for fastening cards within theholder A.

The bottom of the box A is made with a longitudinal slot or groove a,within which is arranged the clamp B. The clamp B comprises a body I)provided at each side with a wing or lip b, and these two lips extendunder the side edges of slot at and into grooves a formed at each sideof the slot. Also the body Z2 is made with two clamping jaws b which areflexibly connected at 6* with the body b so that said jaws may be spreadapart and allowed to spring together to set and unset the clamp bybending at b. Each jaw' b is made with a pair of wings which embrace theadjacent edge of the slot at, the wings b and Z serving to slidably holdthe clamp in slot a of the holder A by engagement with the edges orsides of said slot. At h the body I) is recessed or bent downwardly toprovide a passage across the body 6 for the rod E.

At one end the clamp body I) carries a pintle which pivotally connectsthe clamp operating member C to the clamp B. The clamp operating memberC is a metal plate provided with pintle sockets 0 to receive the pintleb and perforations c to receive screws 0 by means of which the followerD is secured rigidly to said clamp operating member 0. Also this clampoperating member is made with a pair of downwardly extending wings awhich are perpendicular or vertical at their ends 0 but divergeoutwardly toward their ends 0 It will thus be seen that when the clampoperating member O is lifted on the pintle 6 into the position shown inFigs. 5 and 7 the jaws b will spring inwardly and the clamp will beunset, but when the clamp operating member C is'swung on pintle bdownwardly into the position shown in Figs. 1, 2 and 6 the divergingWings 0 will wedge the jaws b outwardly against the edges of said slotor as shown in Figs. 2 and 6, thereby setting the clamp and locking thefollower D in position. The jaws b are bordered at their inner sides bydepending flanges or lips 7)8 so that as the lower edges of the wings 0pass below the plane of the top of the jaws Z2 they remain in contactwith the lips or flanges b and the clamping pressure is therebysustained. The clamp B and its operating member C are so arranged withrelation to the contents of the holder A, inclicated at a", that thepressure of the latter on the follower D tends to hold the clamp set.When, however, it is desired to unset the clamp to shift the followeralong the slot a, this may be accomplished by a slight forward movementof the follow-er D on pintle sufficient to relieve the pressure of thejaws 6 upon the sides of the slot at. The

' clamp B frictionally engages the sides of the slot a when it is set,and therefore the follower D is held in place through that frictionalengagement, but it will be clear that the follower D of my improvedfiling case does not itself frictionally engage the holder A. That is,in my improved filing case the follower D is held in place by thefriction between the adjustable followercarrying clamp slide B and thecasing of the holder A, and the clamping eifect is produced by thetilting movements of the follower acting through the clamp operat ingmember C.

lVhat I claim is 1. A filing case comprising a holder; a clamp slidablyconnected with the holder comprising two opposed relatively movable jawsfor engaging a fixed part of said holder; a jaw operating member movablyconnected with the clamp, and a follower connected with the jawoperating member, the jaw operating member being arranged between thetwo jaws of the clamp so as to move said jaws relatively to set andunset the clamp when the follower is tilted bodily.

2. A filing case comprising a holder, a clamp slidably connected withthe holder; a wedge shaped clamp operating m mber pivotally connectedwith the clamp, nd a follower connected with the clamp operating member.

3. A filing case comprising a holdtr; a clamp slidably connected withthe holder comprising two separated jaws; a wedge shaped clamp operatingmember pivotally connected with the clamp and adapted when swung on saidpivot to be moved into and out of position between said jaws so as toset and unset the clamp, and a follower connected with the'clampoperating member.

4:. A filing case comprising a holder made with a longitudinal slot; aclamp slidably mounted in said slot and comprising a pair of aws forengaging the sides of the slot;

a clamp operating member pivotally connected to the clamp and adapted tobe swung into and out of position between the jaws to set and unset theclamp, and a follower connected with the clamp operating member.

'5. A filing case comprising a holder made with a longitudinal slot; aclamp slidably mounted in said slot, said .clamp being made with wingsengaging the sides of the slot so as to hold the clamp in place withinthe I latter and with a pair of jaws for engaging the sides of the slot;a wedge shaped clamp operating member pivotally connected to the clampand adapted to be swung into and out of position between the jaws to setand unset the clamp, and a follower con nected with the clamp operatingmember.

In testimony whereof, I have hereunto subscribed my name this 24th dayof September, 1910.
